In this charming and witty romantic comedy two of the most appreciated Latin American actors Mercedes Morán and Ricardo Darín play a middle age couple going through an existential crisis. After 25 years of marriage, Marcos and Ana question themselves deeply on the subject of love, the nature of desire and faithfulness, making a decision that will change their lives forever. The single life may seem fascinating at first, but sooner or later it will become monotonous to her, and almost a nightmare to him.
